Description

Hybrid vehicle and its temperature controlled method of execution

Technical field

This disclosure relates to a kind of hybrid vehicle and its temperature controlled method of execution, and more particularly, to one The mode that kind can be effectively carried out heating by predicting the stopping of hybrid vehicle in cold snap changes controlling party Method, and execute the hybrid vehicle of this method.

Background technique

In recent years, with the stringent rule to the continuous demand and many countries for improving vehicle fuel efficiency to vehicle discharge Fixed, the demand to environment-friendly type vehicle has increased.As the example of this environment-friendly type vehicle, hybrid electric has been developed Vehicle (HEV) and plug-in hybrid electric vehicle (PHEV).

Hybrid vehicle is travelled using two power sources including engine and motor.In engine and electricity In the case where motivation coordination operation, optimal output and torque can be generated.Specifically, equipped with parallel connection type or TMED type (the electric device type for being equipped with speed changer) hybrid power system (is equipped with motor and is started between engine and speed changer Machine clutch (EC)) hybrid vehicle in the case where, the output of engine and the output of motor can be passed simultaneously To drive shaft.

In general, hybrid vehicle uses electric energy traveling (that is, EV mode) in the initial stage of acceleration.However, being used only There is limitation come power needed for providing driver in electric energy, it is therefore desirable to use engine as main power source at certain moment (that is, HEV mode).In this case, when the difference between the revolutions per minute of motor and the revolutions per minute of engine When within a predetermined range, hybrid vehicle is operated so that engine clutch engages, so that motor and engine revolve together Turn.

Certainly, even if under HEV mode, engine may also be not used as main power source.For example, in the parallel connection of HEV mode In mode, the power of engine is used as driving force.However, engine is driven at low load under cascaded H EV mode, because The driving force of this engine be used to generate electricity.The driving point and effect of HEV mode and cascaded H EV mode in parallel will be described referring to Fig.1 Rate.

Fig. 1 (the relevant technologies) is the relationship indicated according to the driving point for the HEV mode for generally mixing with power car with efficiency Figure.

Fig. 1 illustrates that the braking rate of fuel consumption figure (BSFC) of engine efficiency, wherein horizontal axis indicates engine RPM, the longitudinal axis Indicate car speed.The center of efficiency towards circle ISO efficiency curve gradually increases.

As shown in Figure 1, parallel drive region 10 is set in the region of relative efficiency.On the contrary, in view of that will generate electricity Motor (for example, mixing starter-generator (HSG)) vibration, noise and output, series connection engine driving region 20 is usual It is set in the low region RPM 1100 to 1300.

On the other hand, in the vehicle issued recently, Full-automatic temperature control (FATC) unit is responsible for executing temperature control. In hybrid vehicle, as needed, FATC performs control to the engine coolant using the heat by engine Carry out heating indoor air.More specifically, when not installing positive temperature coefficient (PTC) heater in hybrid vehicle, or When the ptc heater for being mounted with to have low capacity, FATC can determine the use of engine coolant.At this point, when engine is cold But when the temperature of agent is lower than water temperature needed for heating, FATC requests mixed control unit (HCU) to operate engine.

Then, HCU operates engine, and selects any one of paralleling model and series model according to situation.However, such as It is upper described in reference diagram 1, since paralleling model is more more excellent than series model in terms of engine efficiency, when paralleling model be can Can when (when vehicle at a predetermined velocity more than when driving), can preferentially select paralleling model.

However, when of short duration parking occurs under paralleling model, and the based on engine driving point during down time When drive mode is changed into series model, inefficient control result has been obtained.This will be described referring to Fig. 2.

Fig. 2 (the relevant technologies) is shown in generally mixing with power car since the HEV mode based on car speed changes The figure for controlling and leading to the problem of.

Fig. 2 shows upper figure and the following figures.The horizontal axis of the two figures indicates the time, and the longitudinal axis of upper figure indicates car speed, under The longitudinal axis of figure indicates the driving mode of hybrid power system.That is, the minimum point of the longitudinal axis indicates EV mode, intermediate point in the following figure Indicate HEV mode, highest point indicates HEV mode in parallel.

With reference to Fig. 2, parallel connection is able to enter when rear vehicle speed of setting out in the state that vehicle stops under series model reaches When the value of mode, the driving mode of vehicle be can change as paralleling model.Even if when vehicle during paralleling model downward driving because Traffic signals and stop the relatively short period when, if being unsatisfactory for being able to enter the vehicle speed of paralleling model because of parking Degree, then the driving mode of vehicle temporarily changes to series model.As a result, arriving series model due to changing, engine is in parking Between during poor efficiency driving point place operation, and due to engine output it is low, coolant temperature raising it is unobvious.

That is, the parameter quilt in the case where modifying model by external device (ED), as the input value for study It is transferred to remote information processing center or Cloud Server.Therefore, being modified by study to model is executed by external device (ED) , and only final mask is transferred to vehicle.

Fig. 5, which is shown, according to an embodiment of the present disclosure determines patrolling for parking characteristics using recent acceleration/deceleration prediction model The example collected.

With reference to Fig. 5, mixed control unit 140 according to an embodiment of the present disclosure according to the APS or BPS of driver manipulate come Current driving demand is analyzed, and calculates required torque (S1).Mixed control unit 140 based on current desired torque and BPS manipulates the current movement to determine vehicle, such as whether vehicle currently stops (S2).

Driver's acceleration/deceleration fallout predictor 130 is added to export about driver using recent acceleration/deceleration prediction model Speed/deceleration intention predictive information, and mixed control unit 140 can be by predicting recent torque (that is, required torque is predicted Value) predict the movement (S3) of vehicle.As a result, when be combined with vehicle current movement and will be in the movement of the vehicle occurred in the recent period When, whether can be stopped according to vehicle and whether vehicle will determine whether current parking is of short duration parking setting out in the recent period.

For example, when current vehicle speed is less than first threshold and required torque predicted value is greater than second threshold, due to Vehicle currently stops, but will accelerate in the recent period, thus may determine that of short duration parking.As another example, when vehicle stops At intersection, traffic signal information can be obtained from driving information detector 110, whether to change in the recent period according to signal To predict down time.As another example, when congestion section on a highway distance in short-term, that is, leave congestion section When the required time is less than third threshold value, or when the Distance Remaining in congestion section is less than four threshold values, it can predict of short duration Parking.

Required torque predicted value can be calculated by driver's acceleration/deceleration fallout predictor 130, or as set forth above, it is possible to It is calculated by mixed control unit 140.It, can be by for generating required torque predicted value although being not shown in the accompanying drawings Independent control unit calculate required torque predicted value.
